How to Enable and Use Dynamic Lock on Windows 11

Dynamic Lock is a built-in security feature in Windows 11 that automatically locks your PC when you move away with a paired Bluetooth device, usually your smartphone. Instead of manually locking your computer every time you step away, Windows uses Bluetooth proximity to detect when you are no longer nearby and secures the system automatically.

This feature is especially useful in work environments, shared spaces, or home offices where leaving your PC unlocked can pose a security risk. Once set up correctly, Dynamic Lock works quietly in the background and requires no additional interaction during daily use.

Enabling and using Dynamic Lock on Windows 11 involves pairing a Bluetooth device, configuring sign-in options, and understanding how the feature behaves in real-world scenarios. The steps below explain how to set it up properly and use it effectively.

How to Enable and Use Dynamic Lock on Windows 11

The steps in this section walk you through enabling Dynamic Lock, pairing a compatible device, and understanding how Windows uses Bluetooth distance to lock your PC automatically. Follow the steps carefully to ensure reliable behavior.

Restart the system where instructed so changes take effect properly.

1. Pair Your Phone or Bluetooth Device with Windows 11

Dynamic Lock requires an active Bluetooth connection.

1. Turn on Bluetooth on your phone.
2. Press Windows + I to open Settings.
3. Go to Bluetooth & devices.
4. Turn on Bluetooth.
5. Click Add device.
6. Select Bluetooth.
7. Choose your phone from the list and complete pairing.
8. Confirm the device shows as Connected.

A stable Bluetooth pairing is required for Dynamic Lock to work.

2. Enable Dynamic Lock in Sign-In Settings

Dynamic Lock must be enabled manually.

1. Open Settings.
2. Go to Accounts.
3. Select Sign-in options.
4. Scroll down to Dynamic Lock.
5. Check Allow Windows to automatically lock your device when you’re away.

Once enabled, Windows begins monitoring Bluetooth proximity.

3. Ensure a Lock Screen Sign-In Method Is Configured

Dynamic Lock relies on standard lock screen behavior.

1. In Sign-in options, confirm that a PIN, Password, or Windows Hello method is set.
2. Avoid automatic sign-in configurations that bypass the lock screen.

Without a valid sign-in method, Dynamic Lock cannot function correctly.

4. Keep Bluetooth Active and Stable

Dynamic Lock depends on consistent Bluetooth connectivity.

1. Ensure Bluetooth stays enabled on both the PC and phone.
2. Disable aggressive battery-saving modes on your phone.
3. Keep the phone within normal Bluetooth range during testing.

Unstable Bluetooth connections can delay or prevent locking.

5. Test Dynamic Lock Behavior

Testing confirms the feature is working as expected.

1. Unlock your Windows 11 PC.
2. Leave the room with your paired phone.
3. Wait approximately 30 to 60 seconds.
4. Return and check whether the PC locked automatically.

Dynamic Lock is not instant and may take up to a minute to activate.

6. Understand How Dynamic Lock Works in Daily Use

Dynamic Lock is proximity-based, not motion-based.

1. Windows locks only after Bluetooth signal weakens or disconnects.
2. Walls, distance, and interference can affect timing.
3. Dynamic Lock does not unlock the PC automatically when you return.

Manual sign-in is always required for security.

7. Combine Dynamic Lock with Manual Locking

Dynamic Lock works best as a backup security layer.

1. Use Windows + L when leaving your desk intentionally.
2. Allow Dynamic Lock to handle accidental walk-aways.

This combination provides stronger overall protection.

8. Adjust Power and Bluetooth Settings if Needed

Power management can interfere with Bluetooth.

1. Open Device Manager.
2. Expand Bluetooth.
3. Right-click the Bluetooth adapter and open Properties.
4. Go to the Power Management tab.
5. Uncheck Allow the computer to turn off this device to save power.
6. Restart the system.

This improves Bluetooth stability for Dynamic Lock.

Final Thoughts

Dynamic Lock on Windows 11 is a simple yet effective security feature that automatically protects your PC when you step away. By pairing a Bluetooth device and enabling the feature in sign-in settings, you can reduce the risk of unauthorized access without changing your daily workflow.
